This issue is not limited to Firefox or even the control key. When scrolling and then coasting in one application and then using alt-tab to switch to another application, often the coasting continues.
For example, begin scrolling a long web page in Firefox and let it coast. While it is still coasting, press alt-tab but don't release the alt key. Every time I do this, the highlighted application in the application switcher 'coasts' right or left (depending on whether I am coasting up or down) and then slowly stops after a couple of seconds. Here is another (less reproducible) example. I began scrolling and coasting in Terminator, then pressed alt-tab to switch to Image Viewer (eog) and the picture I had open zoomed out, which is the 'scroll down' action in Image Viewer. Perhaps what I am describing is a different bug, but if so, I it seems closely connected. The way coasting is done seems fragile. It might be that the fix is simply to stop coasting when any key is pressed, or it might be a lot more complicated than this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/803348 Title: In Firefox, scrolling and then pressing Ctrl causes zoom To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/803348/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
